I have the following Code:

Dynamic[Which[infoquestion == "Yes", 
"Please select the calculator that fits your needs best from our \
page", infoquestion == "No", 
"Thanks for visiting us. Please contact our team at +41 77 777 77 \
77 if you want to set up the loan.", True, "Please choose Yes or No"]]

My problem is, that I need to show "Please choose Yes or No", before something is evaluated without pre-defining the variable infoquestion. Is that somehow possible? I tried with True, but this does not apply to unevaluated input.

Dynamic[Which[infoquestion === "Yes", "Please select the calculator that fits your needs best from our page",
  infoquestion === "No", "Thanks for visiting us. Please contact our team at +41 77 777 77 77 if you want to set up the loan.",
  True, "Please choose Yes or No"]]

Which remains unevaluated if it cannot determine the True or False value of its conditions. However, === (SameQ) is perfect for this, as it is guaranteed to evaluate to either True or False for any input based on structural equivalence. == notably does not make this guarantee as it would interfere with its usage in symbolic algebra.
